Specification of Letters Patent. Application filed March 28, 1910.Serial No. 552,011.

To all whom it may can 069%:

Be it known that we, MARTIN HELGEBON and OLAUs HELoEsoN, citizens of theUnited States, residing at Madelia, Minnesota, have invented certain newand useful Improvements in Harvesters; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to harvesters and, in particular, to mowingmachines for the nipping of standing grain, grass and the li e.

The object of the invention is to provide a machine of light draft, asnoiseless as practicable in operation, adapted to use on uneven groundor on a hillside, easily-adjustecl to such inequalities from the driversseat, one that will with full efficiency cut close to or at aconsiderable distance above the ground, and that can readily pass clearof obstructions such as stones and stumps.

The objects of the invention are attained by employing an endless cutterin conjunction with certain adjustable connections which enable thefinger bar to be tilted about its longitudinal axis and to be raisedbodily with the cutter and also inclined in either direction through awide range without detracting in any way from the elliciency of thedriving connection or the operation of the cutter.

The invention, set out in the claims, scribed by reference drawings,wherein Figure 1 is a perspective view of a mower embodying theinvention; Fig. 2 is a top plan with the gear cover removed; Fig. 3 is aside view; Fig. 4 is a fragmentary view showing the cutting mechanismelevated bodily; Fig. 5 is a similar View with the cutter adjusted tomow upon the downward slope of a hillside; Fig. 6 shows the adjustmentto operate on an upward slope; Fig. 7 shows the cutter elevated to clearobstructions or travel to and from'the field; Fig. 8 is a fragmentaryview showing the finger-bar tilted to depress the guard fingers; Fig. 9is a similar View with the guard fingers elevated; Fig. 10 is a sectionthrough the supporting arm; Fig. 11 is an enlarged detail of thefinger-bar cut away to show the construction of the cutter; and Figs. 12and 13 are details.

The harvester as illustrated comprises a as hereinafter particularlywill now be fully debracket has oppositely hounds and tongue.

to the accompanying carriage 1 having'an axle 2 supported by thePatented Mar.25,1913.

wheels 3 and rigidly connected with the tongue 4 by the hounds 5,-thedrivers seat 6 overhanging to the rear as is usual to compensate in ameasure for the weight of the cutting mechanism in front. A bracket 7extends forwardly from the hounds on the inner side of the carriage oropposite that from which the finger-bar projects. This disposed,inwardly projecting pintles 8 and 9 which serve as bearings for thetrunnions 10 and ll'carried by the two branches 12 and 13 of the tubularsupporting arm 14. The arm 14 extends across in front of the carriageframe for a distance substantially coextensive with the width of thecarriage, and being pivoted at its inner end upon the pintles 8 and 9may swing in a vertical plane at right angles to the direction ofmovement of the carriage, and is uided in such movement within the guiderame 15 Anti-friction rolls 16 arranged on each side of the arm 14 andbearing against the inner face of the guideframe provide for the easyoperation of the same. A lever 17 fulcrumed to the tongue 4 at 18, isconnected with the arm 14; by means of the chain 19, and serves to raiseand lower or hold the arm in any desired position by engagement with thesegment plate 20 on the side of the tongue. Upon the outer end of thearm 14, beyond the guide-frame, is rotatably mounted a hub 21 havingstuds 22 and 23 projecting from each side thereof parallel to the axisof the hub. This hub has rigidly attached thereto a lever 24 by means ofwhich the same may be rotated upon the arm 14: and held in any desiredposition by engagement with the segment plate 25, secured on the outerside of the standard. 26, carried by the arm.

yoke 27 embraces the two studs 22 and 23 in its medial portion and ispivoted thereon at 28. At the top ofthe yoke is arranged a chain or thelike 29, and this, in turn, is 'oined by a flexible connection such as achain or rope 30 passing around the pulley 31, upon the standard 26, toa lever 32, fulcrumed upon the standard and held in any adjustedposition by a segment 33 upon the inner side of the standard.

The lower extremity of the yoke 27 has rigidly affixed thereto the innershoe 34 of the finger-bar 35, and the latter is therefore rigidly heldat substantially right angles to secured to the carriage too . and 40near the extremes of the bar.

the yoke 27 and is tilted upon the pivots 28 by the operation of thelever 32 so as to hold the finger-bar at an inclination adapted to ahillside or declivity. The finger-bar 35 therefore extends laterallybeyond the carriage for its full length and is held rigidly at rightangles to the direction of movement of the carriage but is freelyadjustable within a vertical plane. Upon the outer ex- 'tremity of thefinger-bar is fixed a shoe 36 about the chain-wheels 44 and 45,-theformerrigidly mounted in the inner recess and= the latter adjustablymounted in the outer re; cess within a clevis '46 having a threaded"bearing by means of the bolt 47 in the outer shoe. The chain-wheelsrotate and the chain travels 'in'a horizontal plane with their upperfaces substantially flush with the upper face of the finger-bar. Guardfingers 48are arranged at intervals along the forward edge of thefinger-bar and are securedthereto below by strap runners 49 and above byplates 50, let into the upper face of the finger bar and secured to thesame and t0 the guard fingers. An endless cutter is formed of segments51, firmly secured along their inner edges to the chain links andresting upon the upper face of the finger-bar in the rear and upon theplates 50 in front. Being attached .to the chain these segmentsconstitute an endless cutter traveling between the inner and outerextremities of the fingerbar in an' endless path over the upper face ofthe bar and between the guard fingers upon the plates and serve to cutthe stand' ing grain, grass or the like in the path of the finger-bar; Acover-plate 52 overlies the cutter and is removable as a whole, but isalso preferably provided with a hinged section 53 giving access to theinterior mechanism.

The manner of insertion and removal of the chain with its cuttersegments will be obvious from an examination of Fig. 13. In the outershoe 36 is removably seated a slide 36 which, when removed by looseningthe screw fastening 36*, leaves a channel 36 in line with the chaingroove 42. To remove the chain for any purpose, the machine being out ofgear, the hinged cover 53 is opened and the chain pulled around by handor a suitable hook until the usual coupling link appears and isuncoupled. The chain is then pulled around until its end is in line withthe channel 36, when by the hook it can be drawn out through thechannel. To replace, the operation is reversed, the chain being insortedthrough the channel pushed in until its first link engages with theteeth of the chain wheel 44 which is turned to draw the chain entirelyin and the ends of the are brought tothe point where they wereuncoupled. They'are then coupled together,

the slide 36 replaced and the cover 53 closed, when the machine is readyfor operation. 1

The cutter mechanism is driven, as is usual, from the drive wheels ofthe machine, the axle 2 carrying splined thereon a clutch member 54yieldingly pressed by the spring 55 into engagement with-the secondclutch member 56, carried by the drive pinion 57.

The pinion 57 may be thrown into'or out of gear by means of the lever.58-fulcrumed at 59, and bearing with one arm against the clutch member 54,the other arm provided with ahandle 60 arranged to hold the clutchmembers apart when in engagement with the ratchet 61. e

A drive shaft 62, j ournaled in the carriage and passing centrallythrough the pintle 8, is provided on its inner end with the beveledpinion 63 meshing with the drive pinion 57 and upon its outer end withthe pinion 64, meshing with the pinion 65, carried by the inner end of atransmission shaft 66,

which is journaled within and extends the full length of the supportingarm 14. The outer end of the transmission shaft has formed thereon a.knob 67 with oppositely arranged longitudinal recesses 68 for thereception of balls 69 mounted in recesses in theinner face of a socketplate70, carried, together with a pinion 71, by the stub shaft 72,journaled in a bracket 73, rigidly secured to the inner shoe 34 of thefinger-bar and to the yoke 27. This pinion 71 meshes with another pinion74, fixed upon the axle of the inner chain wheel 44.

It will be seen that the supporting arm 14 is so pivoted in line withthe axis of the drive-shaft that its pinion 65 maintains a sal jointbetween the transmission shaft and the beveled pinion, driving the chainwheel and composed of the knob 67 and the socket 70, enables the fingerbar with its mechanism to be tilted about the pivot 28 and also enablesthe same mechanism, together with the yoke 27, to be turned upon the arm14 without disturbing the driving connection between the transmissionshaft and such mechanism. a V

The combined mechanism whereby the finger-bar may be tilted upon an axistrans verse to the direction-of movement of the machine by the partialrotation of the hub plate 70 to the pinions tion.

21 and also upon an axis longitudinally of the movement of the machineupon the pivots 29, is greatly assisted and the delicacy of adjustmentenhanced by the provision of the long supporting bar 14, by means ofwhich the finger bar and itsmechanism may be also raised bodily withoutdisturbing its independent adjustments, the movement of such arm beingabout a pivot removed the full 'width of the carriage from the inner endof the finger bar. 1

The operation 'of the harvesting machine is as follows: The clutchmembers 54 and 56 being in engagement during the forward movement of theharvester, the motion of the driving wheels 3 is transmitted to thedrive pinion 57 and thence through the drive shaft 62 and its beveledpinions 63 and 64, and the pinion 65 to the transmission shaft 66,thence by, the 'universal conknob 67 and socket 71 and 74 and the axleof the inner chain wheel 44, whereby the chain wheel 43 with its cuttersegments 51 is driven in an endless path longitudinally on the fingerbetween the guard fingers 48. On level ground the finger bar may belowered until it rests upon the strap runners 49 with the cuttertraveling close to the ground and leaving a very short stubble. Theheight of the stubble may be further reduced by tilting the finger barforward upon its longitudinal axis by operating the lever 24 topartially rotate the hub 21; or the length of the stubble may beslightly increased by tilting the finger bar backward upon itslongitudinal axis if the lever 24 be moved in a reverse direction. Bythis adjustment the horizontal position of the finger bar is notaffected. If it is desired to leave a longer stubble, the finger bar maybe elevated bodily by operating the lever 17 to elevate the supportingarm 14 and hold the same with the finger bar at the desired elevationand horizontal.

In case the machine is used to mow-upon the incline of an elevation ordeclivity, adjustment is efi'ected by means of the lever 32 acting uponthe yoke 27 to tilt the finger bar about the pivotal point of the yokeso that the same shall project from the carriage downward or upward atan inclina- To out upon a downward-slope the lever 32 is thrown forwardand the weight of the outer end of the finger bar causes the same todrop; on the other hand for use upon an upward incline the lever 32 isdrawn backward toward the operator and its flexible connection 30 withthe yoke 27 lifts the free outer end of the finger bar to theproperdegree of elevation. The adjustment of the finger bar to out upon adownward or u per slope can be further accentuated by li ting the fingerbar bodily, while in its innection composed of the bar 35, cutting thegrain.

eration, the lever clined position, by means of the supporting arm .14through its-lever 17 in order to cut more or less closely to the groundand also {0 cdpnform to changes in the contour of the an To clearobstructions near the inner end of the finger bar both the levers 17 and.32 would be operated, the former to lift the inner end of the fingerbar and the latter to permit the outer end to drop so that it wouldremain in substantially its original relation to the ground. To clear anobstruction near the outer end of the fin er bar, the lever 32 onlywould be employe to lift the outer end while permitting the inner end toremain. If the obstruction were about the center ofthe finger bar orcoextensive therewith the lever 32 would not be used, but thelever 17would be resorted to to lift the cutting mechanism bodily by means ofthe supporting arm. It will benoted that by reason of the pivoting ofthe arm in line with the axis of the pinion 64 of the drive shaft, andby the provision of the universal connection between the outer end ofthe transmission shaft and the pinion driving the inner chain wheel, theraising and lowering of the supporting arm and the tilting of the yokeor the to secure the various adjustments of the cutting mechanism, donot in any way interfere with the transmission of power from the driveshaft to the cutter, and the various adjustments of the cuttingmechanism may be efiected while the latter is in full operation.

In traveling to and from the place of op- 17 would be operated to liftthe arm 14 and the cutting mechanism bodily, and in conjunctiontherewith the lever 32 would be resorted to to tilt the 'finger bar atan upward inclination to its fullest extent. lin order to thus travelidly also the clutch members 54 and 56 would be thrown out of engagementby means of the lever 58 so that the rotation of the wheels 3 would haveno effect upon the cutting mechanism.
